Solar Industry has come a long way since its inception.
A few years the products used to cost more and the efficiency of the product was very low. But as the world started to change and more and more people started to turn towards sustainable and renewable energy the industry started to develop at a rapid pace. The solar cells and panels these days are way better than what they used to be before.
These days from many largescale industries to even small households have started to make use of solar energy. There has been a steady rise in demand and the technology is in a very rapid growth phase. Solar cells these days have so much efficiency and the prices are low that people now buy them. Though they are much weaker compared to solar crystalline panels they have around 34% efficiency which is good for its cost. These simple devices have two distinct mechanisms. One is the way these cells absorb the light from the sun while the other is how the energy is then converted into electricity. With the latest technology, these mechanisms have improved from what they used to be. They use two different films with different material coating for this process. One with CIGS (copper, indium, gallium, diselenide and CZTSSe which is copper zinc tin sulfur selenide is used.
Due to the rapid exhaustion of nonrenewable resource and the effect it has on the environment different countries across the globe have started to support such projects. At the current pace we are moving ,we will have exhausted all our resources in a couple of decades or so. The rapid change in climate and the increase in temperature is also quite alarming. It has resulted in the melting of icebergs; the sea levels are also rising. When we have a better energy source such as solar energy it is best to switch now rather than later when it will be too late. The source of energy involved here is endless as there is sunlight available each day.
At this point, every choice we make will matter. So, let’s join hands and join the revolution to go green and go healthy thereby preserving the world for future generations to come.
